Abstract
Description
Die vorliegende Erfindung betrifft einen Stützkörper, insbesondere zur elastischen Abstützung eines Sitz- oder Liegeelementes, mit einem insbesondere einstückig aus Kunststoff hergestellten Federelement mit einer in Bezug auf die Federachse oberen Stützfläche, einer unteren Stützfläche und mindestens zwei von der oberen Stützfläche zur unteren Stützfläche verlaufenden, elastischen Federstreben, die zwischen oberer Stützfläche und unterer Stützfläche jeweils mindestens einmal derart abgewinkelt oder gebogen ausgebildet sind, dass sie sich ausgehend von der unteren Stützfläche zunächst in eine erste zur Federachse geneigte Richtung und dann in eine zweite zur Federachse zumindest im Wesentlichen entgegengesetzt geneigte Richtung erstrecken.The present invention relates to a support body, in particular for elastic support of a sitting or lying element, with a particular in one piece made of plastic spring element with an in Reference to the spring axis upper support surface, a lower support surface and at least two from the upper support surface to the lower support surface extending elastic spring struts between the upper support surface and lower support surface each angled at least once or bent, that they are formed from the lower Support surface first in a first direction inclined to the spring axis and then in a second to the spring axis at least substantially opposite extend inclined direction.
Derartige Stützkörper werden beispielsweise als Teil einer Untermatratze mit einer Vielzahl von über mindestens einen Teil der Untermatratze verteilt angeordneten, voneinander unabhängigen derartigen Stützkörpern zur Abstützung einer Obermatratze oder als Federkern einer Obermatratze eingesetzt. In Untermatratzen ersetzen sie in den entsprechenden Bereichen die herkömmlichen Federleisten und haben den Vorteil eine quasi punktelastische Abstützung zu ermöglichen.Such support bodies are used, for example, as part of a lower mattress with a variety of over at least a portion of the under mattress arranged distributed, independent of such support bodies for supporting an upper mattress or as spring core of a mattress top used. In sub-mattresses replace them in the corresponding areas the conventional spring strips and have the advantage of a quasi To enable point elastic support.
Ein Stützkörper dieser Art ist beispielsweise aus der DE 100 04 015.2 bekannt. Das Federelement dieses bekannten Stützkörpers hat den Vorteil, dass sich die oberen und unteren Enden der Federstreben aufgrund ihrer abgewinkelten oder gebogenen Ausbildung in Federrichtung betrachtet bei Belastung des Federelementes nicht voneinander entfernen. Das heißt, die Projektion des oberen Endes jeder Federstrebe auf die Ebene des unteren Endes ändert sich bei Belastung des Federelementes praktisch nicht. Dies hat den Vorteil, dass keine Relativverschiebung der Federstrebenenden quer zur Federachse auftritt, so dass zwischen den Federstrebenenden und einem von diesen abgestützen Gegenstand keine Reibung entsteht. Ein weiterer Vorteil besteht darin, dass die Federstrebenenden eines Federelementes fest miteinander verbunden werden können, beispielsweise zu einer Kopfplatte oder Kopfplattenaufnahme, da sie sich bei Belastung des Federelementes nicht voneinander entfernen.A support body of this type is for example from DE 100 04 015.2 known. The spring element of this known support body has the advantage that the upper and lower ends of the spring struts due to considered their angled or curved training in the spring direction Do not remove from each other when loading the spring element. The That is, the projection of the upper end of each spring strut on the plane the lower end changes practically under load of the spring element Not. This has the advantage that no relative displacement of the Spring strut ends transverse to the spring axis occurs, so that between the Spring strut ends and one of these supported object no Friction arises. Another advantage is that the spring strut ends a spring element can be firmly connected to each other, For example, to a headstock or headstock recording, as they Do not move away from each other under load of the spring element.
Das Federelement des zuvor genannten bekannten Stützkörpers hat außerdem den Vorteil, dass es aufgrund seiner speziellen Ausgestaltung trotz des Vorhandenseins von drei oder mehr um die Federachse verteilt angeordneter Federstreben hinterschnittfrei ausgebildet, also einfach einstückig herstellbar ist. Ein gewisser Nachteil besteht jedoch darin, dass die Formhälften zur Entformung quer zur Federachse bewegt werden müssen und sich verhältnismäßig lange Taktzeiten ergeben. Auch ist die Resthöhe des Federelementes bei vollständiger Kompression aufgrund des sich Übereinanderlegens der in entgegengesetzte Richtungen geneigten Abschnitte der Federstreben noch verhältnismäßig groß.The spring element of the aforementioned known support body also has the advantage that it is due to its special design despite the presence of three or more distributed around the spring axis arranged Spring struts formed undercut, so simply in one piece can be produced. A certain disadvantage, however, is that the Mold halves for removal from the transverse axis to the spring axis must be moved and result in relatively long cycle times. Also, the residual amount the spring element in complete compression due to the Superimposing the sections inclined in opposite directions the spring struts still relatively large.
Der Erfindung liegt die Aufgabe zugrunde, einen Stützkörper der genannten Art anzugeben, welcher diese Nachteile nicht aufweist. Insbesondere soll die verbleibende Resthöhe verringert und die Entformbarkeit des Federelementes verbessert werden. The invention is based on the object, a supporting body of said To specify type, which does not have these disadvantages. Especially the remaining residual height should be reduced and the demoldability of the Spring element can be improved.
Diese Aufgabe wird dadurch gelöst, dass der in die erste Richtung geneigte Abschnitt und der in die zweite Richtung geneigte Abschnitt einer Federstrebe sowie die obere Stützfläche und die untere Stützfläche in Federrichtung betrachtet vollständig nebeneinander angeordnet sind, so dass sie sich nicht gegenseitig verdecken.This object is achieved in that the inclined in the first direction Section and the inclined in the second direction portion of a spring strut and the upper support surface and the lower support surface in the spring direction considered completely juxtaposed, so they do not hide each other.
Durch die vollständig nebeneinander gelegene Anordnung der in entgegengesetzte Richtungen geneigten Abschnitte der Federstreben und der Stützflächen des Federelementes liegen diese bei vollständiger Kompression des Federelementes nicht aufeinander, sondern kommen nebeneinander zu liegen. Die verbleibende Resthöhe des Federelementes bei vollständiger Kompression ist dadurch gegenüber den Federelementen bekannter Stützkörper verringert. Zudem ermöglicht diese Ausgestaltung die Ausbildung eines in Federrichtung hinterschnittfreien Federelementes. Dies ermöglicht eine einfache Entformung mit kurzen Taktzeiten.Due to the completely juxtaposed arrangement of the opposite Directions inclined sections of the spring struts and the Support surfaces of the spring element are these with complete compression of the spring element not on each other, but come next to each other to lie. The remaining residual height of the spring element at full Compression is known to the spring elements Support body reduced. In addition, this embodiment allows training a feather-less under spring element spring element. This allows easy demolding with short cycle times.
Werden die entgegengesetzt geneigten Abschnitte der Federstreben jeweils im Wesentlichen gleich lang ausgebildet, kann ein Versetzen der Federstrebenenden quer zur Federachse zumindest weitgehend vermieden werden. Es tritt daher keine Reibung zwischen den Federstrebenenden und einer von diesen beispielsweise abgestützten Matratze auf. Die Federstrebenenden können bei einer solchen Ausgestaltung auch fest miteinander verbunden werden, beispielsweise über eine Kopfplatte oder eine Kopfplattenaufnahme.Be the opposite inclined sections of the spring struts respectively formed substantially equal length, can be a displacement of the spring strut ends at least largely avoided transversely to the spring axis become. There is therefore no friction between the spring strut ends and one of these, for example, supported mattress. The spring strut ends can also be fixed to each other in such an embodiment be connected, for example via a top plate or a Headstock recording.
Die Federstrebenabschnitte bzw. ihre Projektionen auf die untere oder obere Stützfläche verlaufen bevorzugt zumindest annähernd radial zur Federachse. Sie oder ihre Projektionen können aber auch tangential zur Federachse verlaufen. Die zuerst genannte Variante ermöglicht eine besonders gleichmäßige Verteilung der Federstreben um die Federachse, während die zweite Variante eine spiegelsymmetrische Anordnung um eine die Federachse enthaltende Ebene erlaubt.The spring strut sections or their projections to the lower or upper support surface preferably extend at least approximately radially to Spring axis. You or your projections can also be tangent to the Spring axis run. The first mentioned variant allows a special uniform distribution of the spring struts about the spring axis, while the second variant to a mirror-symmetrical arrangement allows a plane containing the spring axis.
Die entgegengesetzt geneigten Abschnitte einer Federstrebe bzw. ihre Projektionen auf die untere oder obere Stützfläche können nach einer Ausgestaltung der Erfindung parallel zueinander verlaufen. Dies ermöglicht bei tangentialer Anordnung der Federstreben einen kompakten Aufbau des Federelementes.The oppositely inclined portions of a spring strut or their Projections on the lower or upper support surface may be after one Embodiment of the invention parallel to each other. this makes possible with tangential arrangement of the spring struts a compact design of the spring element.
Nach einer anderen Ausgestaltung können die entgegengesetzt geneigten Abschnitte der Federstreben bzw. ihre Projektionen auf die untere oder obere Stützfläche einen Winkel kleiner 90° miteinander einschließen. Dies ermöglicht bei annähernd radial verlaufenden Federstreben ein Verbinden der Federstrebenenden zweier benachbarter Federstreben.According to another embodiment, the oppositely inclined Sections of the spring struts or their projections to the lower or upper support surface an angle smaller than 90 ° with each other. This allows for nearly radially extending spring struts connecting the spring strut ends of two adjacent spring struts.
Die Federstrebenenden laufen nach einer weiteren Ausgestaltung der Erfindung auf einer Seite des Federelementes frei aus und bilden jeweils einen Stützflächenabschnitt. Die gesamte Stützfläche auf einer Seite des Federelementes kann so einfach durch die Federstrebenenden gebildet werden. Die Stützflächenabschnitte könne beispielsweise durch Platten gebildet werden, in welche die freien Enden der Federstreben münden.The spring strut ends run according to a further embodiment of the Invention on one side of the spring element free and form each a support surface section. The entire support surface on one side of the Spring element can be so easily formed by the spring strut ends become. The support surface sections, for example, by plates are formed, in which open the free ends of the spring struts.
Des Weiteren ist es bevorzugt, wenn die freien Enden zweier benachbarter Federstreben jeweils gemeinsam einen Stützflächenabschnitt bilden. Daraus resultieren ein stabiler Aufbau und gute Abstützeigenschaften. Furthermore, it is preferred if the free ends of two adjacent Spring struts together form a support surface portion. This results in a stable construction and good support properties.
Nach einer weiteren Ausgestaltung der Erfindung, die auch für sich beansprucht wird, weisen die Federstrebenenden, insbesondere an diese angeformte Mittel zur Verbindung mit einer Kopf- oder Fußplatte auf. Gemäß dieser Ausgestaltung wird die Kopf- oder Fußplatte selbst also nicht angeformt, sondern separat hergestellt. Dies ermöglicht die Verwendung verschiedener Materialien und vereinfacht die Herstellung. Die Verbindung der Federstrebenenden mit einer Kopf- oder Fußplatte erhöht außerdem die Stabilität des Federelementes.According to a further embodiment of the invention, which also claims for itself is, have the spring strut ends, in particular to this molded Means for connection to a head or foot plate. According to this embodiment, the head or foot plate itself is therefore not formed, but made separately. This allows the use of different Materials and simplifies the manufacture. The connection the spring strut end with a head or foot plate also increases the stability of the spring element.
Eine hohe Kippstabilität ergibt sich, wenn die Federstreben, nach einer Ausgestaltung der Erfindung, im Wesentlichen gleichmäßig um die Federachse verteilt angeordnet sind. Außerdem kann die Kippstabilität erhöht werden, indem vier oder mehr Federstreben vorgesehen sind.A high tilting stability results when the spring struts, after a Embodiment of the invention, substantially evenly around the spring axis are arranged distributed. In addition, the tipping stability can be increased be provided by four or more spring struts.
Nach noch einer Ausgestaltung der Erfindung sind jeweils zwei an ihren Enden miteinander verbundene Federstreben spiegelsymmetrisch zu einer die Federachse nicht schneidenden Ebene angeordnet. Eine etwa bei Kompression des Federelements auftretende Torsion einer Federstrebe oder sonstige Verdrehung quer zur Federrichtung kann so durch die entgegen gesetzte Torsion oder Verdrehung der zugeordneten spiegelsymmetrischen Federstrebe ausgeglichen werden.According to another embodiment of the invention, two are each at their Ends interconnected spring struts mirror symmetry to a the spring axis is arranged non-cutting plane. An approximately at Compression of the spring element occurring torsion of a spring strut or other rotation transverse to the spring direction can thus by the opposite torsion or rotation of the associated mirror-symmetric Be balanced spring strut.

Das in den Fig. 1 bis 3 dargestellte Federelement weist eine in Federrichtung
I betrachtet untere Stützfläche 1 auf, die durch eine kreisförmige
Platte 2 gebildet wird. An die insbesondere aus Kunststoff bestehende
Platte 2 sind randseitig jeweils mit ihrem einen Ende acht Federstreben 3
angeformt, deren anderes Ende jeweils in eine von vier kreisförmigen
Platten 4 mündet, die gemeinsam eine in Federrichtung I betrachtet obere
Stützfläche 5 bilden. Die untere Platte 2 weist außerdem Ausnehmungen
6 auf, die zur Verbindung mit einer nicht dargestellten Fußplatte oder
einem Träger ausgebildet sind. Die oberen Platten 4 weisen ebenfalls
Ausnehmungen 7 zur Verbindung mit einer hier nicht dargestellten Kopfplatte
auf.The spring element shown in FIGS. 1 to 3 has a spring direction
I considers
Die Federstreben 3 erstrecken sich ausgehend von der unteren Platte 2
zunächst mit einem ersten Abschnitt 3a schräg nach außen und oben und
anschließend mit einem zweiten Abschnitt 3b schräg nach oben und nach
innen zurück. Der erste Abschnitt 3a ist von der Federachse I also weg
geneigt, der zweite Abschnitt 3b jeweils auf die Federachse I zu geneigt,
und beide bzw. ihr Projektionen auf die Ebene der Stützfläche 1 verlaufen
annähernd radial zur Federachse I.The spring struts 3 extend from the
Der Verlauf der Federstreben 3 ist dabei so, dass ihr erster Abschnitt 3a
und ihr zweiter Abschnitt 3b in Federrichtung I betrachtet vollständig
nebeneinander verlaufen, sich also nicht gegenseitig verdecken. Und zwar
verlaufen die beiden Abschnitte 3a und 3b in der Projektion auf die Ebene
der unteren Stützfläche 1 in einem Winkel α < 90°, im dargestellten Beispiel
von ca. 40° zueinander. Die Winkel α benachbarter Federstreben 3
weisen zueinander umgekehrtes Vorzeichen auf, so dass die oberen Abschnitte
3b benachbarter Federstreben 3 abwechselnd aufeinander zu und
voneinander weg verlaufen. Jeweils zwei aufeinander zu laufende obere
Abschnitte 3b münden in eine gemeinsame obere Platte 4. Auf diese Weise
wird ein Federelement mit um die Federachse I gleichmäßig verteilten
Federstreben 3 und oberen Platten 4 erhalten.The course of the spring struts 3 is such that their
Wie man sieht, sind die Längen der unteren Federstreben 3a und der
oberen Federstreben 3b im Verhältnis zueinander so gewählt, dass die
oberen Abschnitte 3b der Federstreben 3 und die diesen zugeordneten
oberen Platten 4 in Federrichtung I betrachtet die untere Platte 2 nicht
überdecken. Das heißt, die oberen Abschnitte 3b der Federstreben 3 sind
etwas kürzer als die unteren Abschnitte 3a. Da sich zudem die Federstrebenabschnitte
3a und 3b in Federrichtung I betrachtet nicht gegenseitig
verdecken, resultiert ein in Federrichtung I hinterschnittfreies Federelement,
welches in Federrichtung I einfach entformbar ist. Das dargestellte
Federelement kann daher kostengünstig einstückig hergestellt werden.As you can see, the lengths of the lower spring struts 3a and
upper spring struts 3b chosen in relation to each other so that the
Außerdem ist erkennbar, dass die beiden über eine gemeinsame obere
Platte 4 miteinander verbundenen Federstreben 3 jeweils spiegelsymmetrisch
zu einer die Federachse I enthaltenden Ebene verlaufen. Eine bei
Kompression des Federelementes auftretende Torsion der Federstreben 3
oder eine Verdrehung quer zur Federachse I der Federstrebenabschnitte
3a und 3b einer Federstrebe 3 gegeneinander wird so durch die entsprechende
Torsion oder Verdrehung der mit dieser Federstrebe 3 verbundenen
Federstrebe 3 ausgeglichen.It can also be seen that the two have a common
Bei der in den Fig. 4 bis 7 dargestellten Variante verlaufen die Federstreben
3 zwischen unterer Stützfläche 1 und oberer Stützfläche 5 tangential
in Bezug auf die Federachse I. Die untere Stützfläche 1 ist durch eine
langgestreckte rechteckige Platte 2' gebildet, in deren vier Eckbereichen
die vier Federstreben 3 außen angeformt sind. Sie verlaufen mit beiden
Abschnitten 3a und 3b parallel zur Längserstreckung der unteren Platte
2'. Auch hier verlaufen außerdem die unteren Abschnitte 3a und die
oberen Abschnitte 3b der Federstreben 3 nebeneinander, so dass sich
diese in Federrichtung I betrachtet nicht überdecken. In the variant shown in FIGS. 4 to 7 extend the spring struts
3 between
Das andere Ende der Federstreben 3 mündet in eine gemeinsame Deckplatte
4', die als Rechteckrahmen ausgebildet ist. Die Federstreben 3
münden jeweils im inneren Eckbereich dieses Rahmens 4. Auf diese Weise
wird auch bei dieser Variante erreicht, dass sich weder die Federstrebenabschnitte
3a und 3b noch die obere Platte 4' und die untere Platte 2'
gegenseitig überdecken, und auch nicht die Federstreben 3 einerseits und
die Platten 2' und 4' andererseits. Auch dieses Federelement ist daher
einfach in Federrichtung I entformbar. Durch die Anordnung der
Federstreben 3 in den Eckbereichen der unteren Platte 2' und der oberen
Platte 4' ist außerdem eine verhältnismäßig große Kippstabilität
erreichbar.
Auch das Federelement gemäß der zweiten Variante ist bevorzugt aus
Kunststoff hergestellt. Die in entgegengesetzte Richtungen geneigten
Abschnitte 3a und 3b der Federstreben 3 können bei dieser Variante
genau gleich lang ausgebildet sein, so dass so gut wie keine Relativverschiebung
der Federstrebenenden bei Kompression auftritt. Außerdem
verlaufen auch hier jeweils zwei Federstreben 3 spiegelsymmetrisch zu
einer die Federachse I enthaltenden Ebene.The other end of the spring struts 3 opens into a common cover plate 4 ', which is formed as a rectangular frame. In this way, it is also achieved in this variant, that neither the
Also, the spring element according to the second variant is preferably made of plastic. The inclined in
Es ergibt sich ein Stützkörper mit einem Federelement, welches einfach
einstückig aus Kunststoff herstellbar ist. Aufgrund der treppenartig versetzten
Anordnung der oberen Abschnitte 3b und der unteren Abschnitte
3a der Federstreben 3 sowie der auch im Übrigen nicht vorhandenen
Überdeckung der Federelementteile ist eine einfache Entformung in Federrichtung
I möglich. Dies ermöglicht kurze Taktzeiten bei der Herstellung.
Durch die treppenartig versetzte Anordnung der Federstrebenabschnitte
3a und 3b ist zudem die Resthöhe des Federelementes bei vollständiger
Kompression sehr gering. Sie wird nur durch die Materialstärke der Federstreben
3 und der Platten 2, 2' sowie 4, 4' bestimmt. This results in a support body with a spring element, which is easy
can be produced in one piece from plastic. Due to the stepped staggered
